STA@ PATENT BERNARD JACQUART, 0F SOUTH RIVER, NEW JERSEY, AND JOHN V. V. BOORAEM, OF NEW YORK, N. Y.

CLAY-CLEANER.

rosas-fio.

b all whom t 'may conce/ra.

Be it known, that we, BERNARD Jac- QUAn'r and Jol-IN V. V. Boonaniw, both citizens of the United States, and residents, respectively, of South River, in the county of Middlesex and State of New Jersey, and the city of New York, borough of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Clay-Cleaners, ot' which the following is a specification.

This invention relates to clay cleaners, and more particularly to improvements in knives used in such clay cleaners, and the object of the invention is to provide an improved knife, which might be readily adjusted in position, and readily removed for repairing and cleaning and sharpening,

A further object is to provide means for properly adjusting the knife.

In the use of knives in clay cleaners it very often happens that a space between the knife and the support for the clay to be cut,

is filled with small pebbles, which so clog` the space as to render the knife useless m a large degree, and it also happens that the extreme wear and tear to which the knives are subjected requires much repairing, and sharpening and readjustment; and a further necessity is to have the knives in parallelism with the support for the clay so as to make an equal cut of the clay, and prevent thereby the knife from being subjected to breaking. The securing of the knives in exact position is quite important, and additional means for adjustment of the knives have, for this reason, been provided.

Our invention further consists in providing knives for clay cleaners with adjustment of the knife in respect to this plate and in adjustment with the plates themselves, and at the same time providing means for enabling the knife with its plate to be turned in position to permit this line adjustment.

In the accompanying drawings, Figure 1 is a plan View of one of the improved knives for clay cleaners, Fig. 2 is a plan view of the same, with the knife turned over bottom up, Fig. 3 is a side View of the knife, Fig. 4L is a vertical transverse section of the rotary plate of the clay cleaner with the knives in position ready to cut, Fig. 5 is an end view of a portion of the plate showing the position of the knife, and, Fig. 6 is a side view of the tripper arrangement.

Similar characters of reference indicate corpus-.pointing parts ot.' the various views.

heteriangto the drawings, and more particularly to l `1g. el., a rotary knife carrier l() of the clay cleaner is provided with a wearingl plate ll, which is secured to the plate by st ntablescrews The plates 111 are provided with .openings 13, as are well known in the art, 1n which openings pivoted knife supports l-ilare arranged, which knife supports have pirotcd shafts at each end thereof, which engage bearings 16 of the carrier 1Q. A bolt 9 holds the parts in position. lhesc shatts permit. the knife supports l-lf to be swung to the position shown in Fig. Q, bottom upward, to enable the knivesriltii to be adjusted in position. The knives are provided with slots 1T, which 'torni guideways for the fastening screws 18, which hold the knives against the knife supports 111.-, by the aid of a fastening plate 19. held in position against thclmife supports by the screws 1S. The fastening plates 19 are provided at their rear end with shoillders 2O to take up the. thickness of the knife 16, the said fastening plates capable of being` used on either side. rlhe knife 161 projects somewhat beyond the knife supports 11i, and is distant from the wearing-plate Q5 a suitable distance, to allow the cut oll' clay to pass therebetween. The tripper wearing plate is made of suitable wearing material, similar to the wearinoplate 1l, and is secured to the tripper 2C liy means of screws 27. These trippers are pivoted at 2S and are provided with extensions 29 connected by a link 30, which is in turn secured to a sjiring 31, secured to the plate l0. An extension 29 is provided with an arm 3Q, which has a de tachable striking plate which .may be struck by a roller 3st, supported on a stationary plate 35 pivoted at 3G to the frame 37 of the machine. A second roller 38 eccentrically pivoted at 39 is operated by a lever 1-.O with an engaging device l1. The object of the operation of the lever L1-0, and eccentric rollers 38 is to place the rollers into operative position, with the wearing plate 33, or in inoperative position therewith. Vvlhen the roller 3-1- is in operative position, the rotating plate strikes against the roller 34, and thereby operates the trippers around their pivots 28 in the direction of the knives, and thereby causes any clogging between the trippers 9G and the knives to be removed. To control the movement of the extensions 29 adjustable bolts 4t2 engaging the carrier 10 are provided. To further insure the adjustment of the knives, the knife carriers 14 are provided with downwardly extending members v50, which are engaged by a screw-threaded pin 51, which is adjustable on the extension 50, and held in position by the jam nut 52. These pins are arranged as shown in Fig. 2, and they permit the adjustment of the pivoted knife earrier in relation to the rotary carrier 10, while the screws 18 permit the adjustment of the fastening plates 19, and permit the adjustment of the knives in proper position. The pivoted supports of the knife carriers permit the turning over of the carriers bottom upward, to enable the knives to be removed for repairing and sharpening.

Ve have shown an embodiment of our invention, but it is clear that changes may be made therein without departing from the spirit of the invention.

We claim:

1. An improved knife for clay cleaners comprising a carrier, pivoted shafts at each end thereof, a knife plate supported on the carrier and having shoulders of knife-thickness at its rear-edge, a knife between the carrier and the knife-plate, and means for adjusting the knife on the carrier radially in and'out from the axis of the carrier.

2. An improved knife for clay cleaners, comprising a reversible pivoted carrier, a

knife radially adjustably secured thereto,

and a set-screw at the lower portion of the knife Carrier for changing its position.

3. A knife for clay cleaners comprising a carrier, having unobstructed movement into reverse position of the knife, a knife fas- 40 tening plate at the lower side thereof, a knife between the Carrier and fastening plate, means adj ustably holdin@ the fastening plate and knife in position, and means for varying the position ofthe knife carrier with the knife thereon arranged to permit free movement of the knife carrier with its knife, from its normal position to a position with the bottom side up.

In testimony, that we claim the foregoing Copies of this patent may be obtained for ve cents each, by addressing the Commissioner of Patente Washington, 2D. C.
